Editing a generated page flips its `origin` to `edited`; it keeps your text until its sources are re-crawled, at which point an update or refresh of the hub regenerates it. Pages you authored (`origin` `user`) keep your edits permanently. The response carries only the fields this call changes; list the hub's pages for a page's category and createdAt. Only the hub's owner can edit pages. Errors: - `404` `KNOWLEDGE_HUB_NOT_FOUND` — No hub with that id, it was deleted, or it belongs to another team. - `404` `KNOWLEDGE_PAGE_NOT_FOUND` — No page with that id on this hub. - `409` `KNOWLEDGE_HUB_NOT_READY` — The hub is still building, or its build never finished. - `409` `KNOWLEDGE_HUB_PAGES_UNAVAILABLE` — The hub predates knowledge pages. - `403` `KNOWLEDGE_HUB_OWNER_ONLY` — You can read this teammate's hub but only its owner can edit pages. - `422` `VALIDATION_FAILED` — Neither title nor content given, or a value too long. - `500` `UNEXPECTED_ERROR` — The edit was saved but could not be re-indexed; retry the PATCH. - `429` `RATE_LIMITED` — More than 30 knowledge-hub/campaign requests in a minute (or 1000 in a day). Knowledge hubs share the campaigns bucket.
